Abstract

Abstract:

This paper numerically analyzes the Ka band slotted waveguide antennas which are involved in engineering using parallel method of moments(MoM). For lack of the match terminator, it is difficult for the MoM to simulate the traveling wave antenna. To deal with this problem, the equivalent principle on the wave ports and the mode match methods are used to construct the model of wave ports. As an improvement, the waveguide and the wave ports are divided into different domains. The affections between the two domains are assumed as the external excitations of each domain. Then, the iteration method can be used to solve the equation. At the same time, the introduction of the parallel calculation technique can improve the ability of the MoM to analyze the electrically large targets. The agreement of the measurement result and numerical result proves that the model of wave ports proposed in this paper can help to solve the problem of the simulation of slotted waveguide antenna validly.
